Recent devstack changes broke redstack

[Peter Stachowski]

A recent commit in devstack (https://review.openstack.org/#/c/219207 ) now validates that all post-processed conf files specified in local.conf exist.

We need to conditionally add the ceilometer.conf to this file, since it may or may not be present.

Enabling Ceilometer is also broken, as it's now a member of the 'big tent' so this needs to be fixed as well

    Fix redstack (devstack changes broke ceilometer)

    A recent commit in devstack (https://review.openstack.org/#/c/219207 )
    now validates that all post-processed conf files specified in local.conf
    exist.

    We need to conditionally add the ceilometer.conf to this file, since it
    may or may not be present.

    Enabling Ceilometer was also broken, as it's now a member of the 'big
    tent' so this was fixed as well

    Two additional options were added to enable ceilometer notifications in
    Nova and Cinder. These can be activated by setting the following on
    the command line or in options.rc (or ~/.redstack.options.rc).

    CEILOMETER_NOVA_CONF=True
    CEILOMETER_CINDER_CONF=True
